It has been assumed that the barrel 6 of the smaller calibre forms the piston rod of the bufling and running out device. The arrangement can, however, be such that it is inserted in the builing and running out device with the provision of'a separate piston rod; also, it may be only surronnded by the cradle of the larger barrel a, the butting and running out device being arranged laterally.

If both barrels are rigidly connected, bending stresses occur in the connecting breech e, on firing from the smaller barrel 6, since the larger barrel a imposes in consequence of its great mass considerable resistance to a rapid acceleration. It the barrels are spring connected by metal or rubber springs, as shown in Figure 3, the recoil movement of the smaller barrel is transmitted without shockto the larger barrel which is gradually brought up to the speed of the smaller barrel, while when firing from thelarger barrel, the smallerbarrel is immediately taken with it.
